Question: Which of the following best describes the effect of allosteric regulation?

Options:

1. It is a permanent change in enzyme structure.
2. It involves binding at a site other than the active site.
3. It only occurs in competitive inhibition.
4. It is only relevant in prokaryotic organisms.

Correct Answer: It involves binding at a site other than the active site.

Solution:

Allosteric regulation involves binding at a site other than the active site, leading to changes in enzyme activity.
